This paper seeks to explain why inflation adjustments still exist. Even though by Decree 1536 of 2007 and Law 1111 of 2006 it is no longer required to enact these adjustments, neither for accounting nor for taxes — this corresponds only to a strictly legal perspective—, we cannot ignore that, as inflation is an economic phenomenon, these facts are not ruled by decrees, maxime when the accounting rule of “essence over form” points out that: “Economic resources and facts must be recognized in their essence or economic reality and not just in their legal form”. This is why inflation must be shown through the notes on financial states; this will imply that inflation adjustments will still have to be done, with statistical, complimentary or extra-accountable goals. In this paper we give theoretical explanations and use Excel as a tool to help solve practical problems in this regards.
